Crematory Tool

Abstract

A blower type tool is designed to be connected to a fluid compressor to provide a stream of fluid that will extract cremains from a crematory, cremation chamber. The tool includes a conduit connected to fluid distribution unit with nozzles to blow fluid against the crematory floor and corners. The nozzles are directed such that the cremains are moved toward and out of the crematory opening. All components of the tool are metal to withstand extreme heat.

         9 . The tool defined in  claim 1  wherein fluid conduit is in fluid communication with the fluid distribution unit through two secondary fluid conduits. 
     
     
         10 . The tool defined in  claim 9  further comprising a fluid compressor in fluid communication with the tube, the fluid compressor capable of providing fluid at 40-60 psi. 
     
     
         11 . The tool defined in  claim 10  further comprising a valve adjacent the upstream end portion to regulate fluid from the fluid compressor. 
     
     
         12 . The tool defined in  claim 1  wherein the fluid distribution unit includes a fluid plenum, and wherein the nozzle comprises a series of ports in fluid communication with the plenum, the ports positioned along a line extending transverse to the axis. 
     
     
         13 . The tool defined in  claim 1  wherein the fluid conduit is at least eight feet in length. 
     
     
         14 . A tool comprising:
 a. a rigid metal fluid conduit having an upstream end portion, a downstream end portion, and an axis extending between the upstream and downstream end portions,   b. a metal fluid distribution unit attached to the downstream end portion, the fluid distribution unit in fluid communication with the fluid conduit, the fluid distribution unit having a length extending at an oblique angle relative to the axis, fluid distribution unit including a nozzle extending generally along the length of the fluid distribution unit,   c. a metal wheel rotatably attached to the fluid distribution unit, and   d. a metal cover extending from the fluid distribution unit toward the upstream end portion.   
     
     
         15 . The tool defined in  claim 14  wherein in the nozzle opens toward the upstream end portion at an acute angle relative to the axis. 
     
     
         16 . The tool defined in  claim 14  wherein in the fluid distribution unit includes a port in fluid communication with the fluid conduit, the port opening in a direction transverse to the axis and generally parallel to the fluid distribution unit length. 
     
     
         17 . The tool defined in  claim 14  wherein in the fluid distribution unit includes a plenum in fluid communication with the fluid conduit. 
     
     
         18 . The tool defined in  claim 17  further comprising a fastener rotatably attaching the wheel to the fluid distribution unit, the wheel having an axis of rotation, the fastener extending coaxially with the wheel axis of rotation, the fastener including a port in fluid communication with the plenum. 
     
     
         19 . A crematory tool comprising:
 a. a rigid metal fluid conduit having an upstream end portion, a downstream end portion, and an fluid conduit axis extending between the upstream and downstream end portions,   b. a metal fluid distribution unit attached to the downstream end portion, the fluid distribution unit in fluid communication with the fluid conduit, the fluid distribution unit including a plenum in fluid communication with the fluid conduit, the plenum having a length, the length defining a plenum axis, the plenum axis extending at a substantially right angle relative to the fluid conduit axis, the plenum including a slit defining a nozzle, the slit extending the length of the fluid distribution unit, the slit opening toward the upstream end portion at an angle of about 70-89 degrees relative to the fluid conduit axis,   c. a metal wheel rotatably attached to the fluid distribution unit, the wheel having an axis of rotation parallel to the plenum axis,   d. a metal sweep member attached to the fluid conduit between the fluid distribution unit and the upstream end portion, and   e. a metal cover extending from the fluid distribution unit to the sweep member.
